I can access the site both from wget and from a browser (Firefox). Are you sure your system is up to date? What versions of wget and gnutls do you use? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Thanks for the response, choroba. All browser software on my various devices is up to date. Also, all apt packages on my two Debian Buster systems are up to date. I can successfully access the docs.raku.org home page in two (inconvenient) ways. 1)If I turn off wifi on my cell phone the docs.raku.org index.html page loads just fine over the cell data network. 2)If I ssh into my web server in a cloud somewhere out there I can wget the index.html page from there as well. All of which leads me to want to look upstream from the individual machines on my local wifi network. So... my Comcast router? I can bring up the admin interface in a browser but I don't know what to look for. Something further upstream? I'm getting out of my depth here. All suggestions welcome. ------------------------------------------------------------ "Perl is a mess and that's good because the problem space is also a mess." - Larry Wall	[reply]

Maybe check the DNS server settings in the router's menu? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Looks like you are connecting via IPV6 - and there may be issues with that. Try using one of the IPv4 addresses below: `Name: docs.raku.org Addresses: 2606:4700:20::681a:f46 2606:4700:20::681a:e46 2606:4700:20::ac43:4429 104.26.14.70 172.67.68.41 104.26.15.70` [download] "The difficult we do today; the impossible takes a little longer."

Thanks, NetWallah. I am assuming that you are suggesting the bottom three addresses in the list you gave. My browser doesn't recognize the top three as URLs. Each of those bottom three addresses gives the same result: `Error 1003 Ray ID: 6651ee569bb639f6 • 2021-06-25 23:21:14 UTC Direct IP access not allowed What happened? You've requested an IP address that is part of the Cloudflare networ +k. A valid Host header must be supplied to reach the desired website.` [download] You said, "Looks like you are connecting via IPV6 - and there may be issues with that." Again, I'm out of my depth here, but is there no way to just say, "Please don't use IPV6" (perhaps just for this site)? And why would IPV6 be a problem? And why would this be happening with just this one particular web site. I do a _lot_ of web reading on a widely varied range of sites -- and this is the only case where this problem has come up. This article: `IPv6 support on Chrome OS https://support.google.com/chrome/a/answer/9211990?hl=en` [download] seemed promising until I remembered that this problem is occurring with Chrome, Vivaldi, Edge, _and_ wget on (variously) Chrome OS, Windows, Android, and Debian. Are the suggestions on that page relevant for all access to IPV6 from this side of my router? ------------------------------------------------------------ "Perl is a mess and that's good because the problem space is also a mess." - Larry Wall	[reply] [d/l] [select]

Here are a few alternatives from ServerFault/StackExchange that you could experiment with to allow access to the Roku site via IP address. I see you have discontinued active discussion on this issue, but , hopefully you have time for a few short tests. "The difficult we do today; the impossible takes a little longer."	[reply]

G'day dvergin, I'm not experiencing any problems. Just for the record, here's what I tried. On Firefox (version 89.0.2): https://docs.raku.org/ works fine; and, `http://docs.raku.org/` and `docs.raku.org` both redirect to that URL. $ wget --version GNU Wget 1.21.1 built on cygwin. ... $ wget https://docs.raku.org --2021-06-26 15:39:21-- https://docs.raku.org/ Resolving docs.raku.org (docs.raku.org)... 104.26.15.70, 104.26.14.70, + 172.67.68.41, ...

Works fine for me using firefox, wget and fetch, but they are all openssl based. You could try to debug your connection directly using gnutls-cli. The output of `gnutls-cli -V -d 3 docs.raku.org` is pretty exhaustive.	[reply] [d/l]
Re^2: [Raku] Cannot Access https://docs.raku.org/ by parv (Parson) on Jun 26, 2021 at 13:58 UTC
There is also gnutls-cli-debug, for overwhelming amount of information.	[reply]

Thanks to all who have chipped in with suggestions and ideas. I had hoped for a quick fix on this. But I fear it has run on rather long on an issue that is only marginally related to Raku programming per se. So I am ready to close this thread out here and take the matter up else where -- starting with Comcast tech support. I have discovered that if I reboot my Comcast router, I can freely load pages from docs.raku.org, as many as I want, for about 20-30 minutes. Then the problem begins, affecting all machines on my lan, and continuing until I reboot the router again. While I pursue a solution elsewhere, I can get by just fine accessing docs.raku.org pages via the Internet Archive.

Hmmm... Perhaps the issue is not IPV6 after all (as suggested elsewhere in this thread). Check this out: $ wget --inet4-only https://docs.raku.org --2021-06-25 18:01:47-- https://docs.raku.org/ Resolving docs.raku.org (docs.raku.org)... 104.26.15.70, 172.67.68.4 +1, 104.26.14.70 Connecting to docs.raku.org (docs.raku.org)\|104.26.15.70\|:443... con +nected. GnuTLS: An unexpected TLS packet was received. Unable to establish SSL connection. $ wget --inet6-only https://docs.raku.org --2021-06-25 18:06:19-- https://docs.raku.org/ Resolving docs.raku.org (docs.raku.org)... 2606:4700:20::ac43:4429, +2606:4700:20::681a:e46, 2606:4700:20::681a:f46 Connecting to docs.raku.org (docs.raku.org)\|2606:4700:20::ac43:4429\| +:443... connected. GnuTLS: An unexpected TLS packet was received. Unable to establish SSL connection. [download] As you can see, the request fails in the same way for both IPV6 and IPV4. So how do I go about diagnosing this failure to access docs.raku.org? It _does_ seem to be related to access through my Comcast router and network (access via my cloud server and via cell data both work fine). It does _not_ seem to be dependent on IPV6 vs IPV4. ------------------------------------------------------------ "Perl is a mess and that's good because the problem space is also a mess." - Larry Wall	[reply] [d/l]

Are you in prison? (That's a joke.) I'm glad you offer the example, because the raku target makes a good canary in coalmine for whether you can do anything with the internet, whether one is 'alive' in some sense.

I wonder if OP has obsolete SSL certificates and/or some issues with GNU TLS (as opposed to OpenSSL (wget -- with OpenSSL 1.1.1k_1,1 -- worked on FreeBSD 13)).	[reply]
